| Abstract: | The effects of anti-seeping curtain with clay-solidified grouting to prevent the pollutants from the seeping wa-ter in the solid-waste landfill were discussed. Under the conditions of high concentration and hydraulic gradient i = 50,the seeping experiments of simulated seeping fluids containing respectively Pb2 + , Cd2+ , CH3 OH and C6 H5 NH2 by solidi-fled-stone of clay-sohdified grouting with thickness 4 cna were completed. The results indicate that the permeability coeffi-cient of simulated seeping fluid of Pb2 + or Cdd2 + is smaller than that of tap water, while that of CH3 OH or C6 H5 NHt2 is abit smaller than that of tap water. The retard efficiency of the solidified-stone to Pb2+ or Cd2+ is more than 99%, toCH3 OH is 95 %, and to C6 H5 NH2 is 85 %. The engineering experiments demorstrate that the efficiency of unit water ab-sorbing of the clay-solidified grouting curtain in base rocks is w <0.003 L/(min·m·m) |
